T all whom it may concern.-

Be it known that I, CHQIMSONOVITZ PROS- PER ELIEsON, a citizen of theRepublic of France, residing at London, England, have 5 invented new andusefullmprovementsin Electrical Accumulators or Storage-Batteries, (forwhich I have obtained patents in the following countries, viz: GreatBritain by Letters Patent N0. 9,522, dated August lO, 1885; in Germanyby Letters Patent No. 35,194, dated October 17, 1885; in .France byLetters Patent No. 175,193, dated April 1, 1886; in Belgium by LettersPatent No. 73,084, dated May p 12, 1886; in Luxemburg by- Letters PatentNo. 685, dated May 16, 1886; in 'the Cape of Good Hope by Letters PatentNo. 6/420, Register No. 356, dated J une 24, 1886; in Italy by LettersPatent XX, No. 19,913, XL, No. 122, dated June 30, 1886; in Victoria byLette'rs Patent No. 4,617, dated July 9, 1886; in South Australia byLetters Patent No. 702, dated July 26, 1886; in New Zealand by LettersPatent No. 1,937, dated July 29, 1886; in Spain by Letters Patent No.dated September 1, 1886;' in New South Wales by Letters of RegistrationNo. 1,919, dated September 6, 1886; in AustriaHungary by Letters PatentN o. 18,560 and No. 47,634, dated September 24, 1886, and in India byLetters Patent N0. 1,557, Register No. 112 of 1886, dated December6,1886,) of which the following is a specification.

The object of my invention is to improve the construction of electricalaccumulators or so-called secondary batteries by providing a very largearea of acting surface without pasting or otherwise attaching salts oflead to the plates before formation,

In order to enable myinvention to be fully understood, I will describethe same by reference to the accompanying drawings, in which- Figures 1and 2.represent front and side views, respectively, of an electricalacc-umulator or storage-battery made according to my invention, the boxor containing-Vessel being shown in section.

In constructing an accumulator according to my invention I use a frame,a, made ordi narily of lead, which is divided or formedinto divisions orcompartments b, of any suitable shape, the divisions or compartmentsbeing shown square in the drawings; but it Will be obvious that they maybe of any other suitable shape. I take a strip of' thin sheet-lead. Uponthe said strip I place another strip of sheetasbestus or other suitableinsulating and acid-proof material. I roll up the strips so as to form acompact spiral, c, cylindrical in shape. Iinsert one of these spirals cinto each compartment or division b in the before-mentioned frame a. Aseries of such frames are arranged in a suitable containing-Vessel, d,as shown in Fig. 2, and I pass a current through them, forming them inthe usual way-that is to say, oxidizing one plate to form -lterminal andhydrogenizing the other to form terminal. l

Among the advantages of my improved electrieal accumulators may bementioned, first, that there are no oxides of lead required to be placedthei-ein, which in a crude form are liable to crumble, and by fallingbetween the plates short-circuit the battery; second, that the spiral asconstructed according to my invention affords a very large actingsurface for electrical storage, whereby such storage may be carried outwithout adding the unnecessary weight, which constitutes a seriousobjection against accumulators when used for electrical traction orother kindred applications where the minimum weight against time-storageis a desideratum; third,that suchacell constructed according to myinvention increases in capacity during its useful life, which is onlyshortened by the disintegration ofthe leaden frame.

Tn the drawings I have shown the spirals a as being of greater lengththan the thickness of the frames a; but such is not necessary, as

2. The combination of a containing-vessel,

Having now particularly described and asa series of frames inclosedWithin said Vessel, certained the natn re of my said invention and andthe spirals c, contained within said frame, in what manner the same isto be performed, I substantially as hcreinbefore described. declare thatwhat I claim is-- 1. A11 electrical accumulator consisting of a frame oflead or other suitable material, coni tainingspirals of sheet-lead,whose surfaces are separated by suitable insulating` and acid-proof Imaterial, substantially as hereinbefore described.

the ends of the spirals may be fiush therewith.
